While many healthy eating guidelines suggest people lower their sodium intake to 2.3 grams of sodium or less per day, global studies have found a “sweet spot” for salt intake — between 3 and 6 grams of sodium per day.


Current maximum sodium recommendations are too low and could even be “unsafe,” according to a new pair of studies from hundreds of researchers including some from McMaster University and Hamilton Health Sciences.

While many healthy eating guidelines suggest people lower their sodium intake to 2,300 mg of sodium or less per day, the global studies have found that people are at risk of heart disease and other ailments when they consume too much or too little sodium.
